UNITED STATES PATENT OFFICEO SAMUEL B. PEAKMAN, OF NEW YORK, N. Y.

SCREW-DRIVER.

SPECIFICATION formingpart of Letters Patent No. 236,692, dated January18, 1881,

Application filed August 23, 1880. (N0 model.)

To all whom "it may concern:

Be it known that I, SAMUEL B. PEAKMAN, of New York, in the State of NewYork, have invented a new and useful Improvement in Screw-Drivers, ofwhich the following is a specification. v

The nature of my invention consists in constructing the screw-d riverand the handle for the same bentin the desired shape out of one piece orrod of steel oriron.

In the accompanying drawings, Figure I represents a front view of myimproved screwdriver. Fig. II is a section at line 00, Fig. I.

I take a bar of steel of the required strength, and flatten one end, I),to form the required shape for a screw-driver. The bar is then bentaround to form a convenient handle for the tool, as shown at a a a. Theend a is slightly flattened and pointed at one side to lie against theside of the bar, and it is then fastened to the same.

The manner of fastening the end 0 to the side of the bar a may be donein various ways. The same may be soldered or riveted to the bar, or theend 0 may be tapered and twisted spirally around the bar a. I prefer forthat purpose a ferrule, n, the opening at the lower end of which is onlyof such a size as to allow the rod a to pass, while at its upper end thesaid opening or cavity is sufficiently large to insert the flattened andpointed end 0 as well as the rod a. This ferrule is placed upon the roda after the end b has received the desired shape of a screw-driver. Therod a is then bent into the desired shape to form the handle, and itsend 0 flattened and pointed, when, after said end 0 is laid closeagainst the side of the rod a, this ferrule n is moved upward and passedpartly over this end 0, so as to confine the same.

I am aware that it is not new to form acorkscrew from asingle piece ofmetal, and I make no claim thereto.

What I do claim is- In combination with bar a, having beveled end 0folded against it to form a handle for the screw-driver, the taperingferrule a, binding said end 0 against the body of said bar,substantially as set forth.

SAMUEL B. PEAKMAN.
